A series of new 1,3,4-oxadiazoles conjugated to aromatic substituents by an azo linker was synthesized in a four-step reaction sequence, involving cyclodehydration of a N,N'-diacylhydrazine fragment and dehydrogenation of the neighboring hydrazine fragment of the intermediate N,N'-diarylcarbonohydrazide.
